Most buzz about quantum computers is how they might be able to break traditional encryption algorithms by fast defactorisation of very big numbers. Though they still owe us proof, that this actually works.

There is this paper, which compares the “big” achievements in quantum defactorisation with a (not really) trained dog. Basically every of these achievements cheated with the prior knowledge of the factors or have chosen convenient numbers, while still being worlds away from common key sizes (like 2048 or 4096 bit).

Real usage for quantum cpmputers will probably still take quite a while to manifest.

Pet by Awaeke Emezi is really good. Partly childish innocence, partly heavy topic about child abuse

And Jamal Khashoggi

Ah, thanks. Thats explains it quite good. Basically everywhere in space we have at least some energy. And where we have enery particles will pop into existance and be destroyed again (photons mostly I guess for low energy like with the background radiation in space). These particles only live a short amount of time, but they can still collide with objects like dust or even planets. And when these objects move, the particles in the front will basically collide harder/more, than in the back. Thus a small force against the moving direction is exerted on the object, proportional to its speed (just like friction). Though this is only significant for small objects like dust or on a very very very long time scale.

What quantum effects exactly? How does that work?

There is a long long way from fewer workhours to all jobs automated

“Less efficient” is quite a misnomer here, since the meshtastic network mainly has to work around the regulations, which leaves it only small timeframes for transmitting. When such a project can only transmit for a few minutes per hour, then naturally it has way less bandwidth overall
